stepIM – Integrated Closed Loop Steppers

With a superior closed loop control and a cost-effective design, the stepIM provides an efficient and economical solution for applications that require the performance of a servo at the price level of a stepper. The stepIM significantly enhances the performance of the stepper motors, when compared to conventional open loop control. The integrated electronics control the stepper motor as a two phase BLDC motor, implementing position servo loop, velocity loop, DQ current control, as well as additional algorithms. Closed loop commutation, by means of an absolute singe-turn encoder, ensures optimal torque utilization at any speed.
